Get matched with top pressure washers in Boulder, MT

Q: How long does a professional pressure washing take?

• <div><p>On average, pressure washing a house can take anywhere from <b>30 minutes to three hours</b>. The time frame to pressure wash or power wash your home, fence, or other property depends on the size of the project and the complexity and accessibility of the areas that need cleaning. Part of the time required to complete the job includes setup and removal of equipment needed. A two-story house with a steep roof may require working from scaffolding or a ladder, likely adding to the time required to finish the project. </p></div>

Q: Is it a good idea to pressure wash a wood deck?

• <div><p>Yes, pressure washing a wood deck can be a good idea as it effectively lifts ingrained dirt, mold, and mildew, improving the deck's appearance and longevity. However, it must be done carefully, as it's easy to damage the wood, especially softwoods. To pressure wash safely, use a lower pressure setting and a wide, 40-degree fan pattern nozzle (often white). Keep the nozzle at least a foot away from the wood surface and maintain constant motion, avoiding hovering in one spot to prevent gouging.</p></div>

Q: Do you turn the pressure washer on before the water?

• <div><p>You should always hook up your pressure washer to the water supply before turning it on and ensure there&rsquo;s a good water flow. If you try to turn the machine on without water in the system, it overworks and overheats the unlubricated pump. This can quickly lead to irreversible damage.</p></div>

Q: When is the best time to pressure wash my house?

• <div><p>Experts agree that spring and fall are the best times to pressure wash a home's exterior due to the milder weather. Aim to schedule the project once a year during a warm, dry season, typically between March and November, depending on your local climate. Many prefer the spring to clean away dirt and grime that has gathered over the winter, preparing the house for the rest of the year. You can always perform touch-ups in the summer or fall as needed.</p></div>

Q: Do I need to winterize my pressure washer and what happens if I don't?

• <div><p>Whether you need to winterize your pressure washer depends on where you store it. If you can keep it in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, if the machine will be stored in freezing temperatures, any liquid left in the water pump can freeze, expand, and cause severe damage. To prevent this, add antifreeze to keep it in good condition. While some suggest emptying the machine with compressed air, this can be a tedious process that may not fully drain the liquid. Regardless of storage conditions, it is also good practice to empty the gas chamber and refresh the oil before winter storage.</p></div>
